This invention relates to certain novel improvements in cutting membersand holders therefor which is especially adapted for use on so calledmeat grinders and the like and 3 has for its principal object theprovision of an improved construction of this character.

which will be eificient in use and economical in manufacture. I I

It is among the objects of my invention to provide a cutting member fora meat grinder .or the like which will embody a holding member in whichthe cutting blades may be removably mounted in order that the blades maybe replaced as required.

nother object of the invention is to provide a construction of the abovedescribed character in which blades will be arranged which will beeasily removable and'which will be constructed so that they may besharpened as required.

A still further object of the invention is to provide a construction ofthe above described character in which the blades will be formed in amanner that will greatly facili- A still further object of the inventionis to provide a blade construction of the above escribed character whichwill embody portions that will permit the interlocking of the blades.Other objects will appear hereinafter. The invention consists in thenovel combination and arrangement of parts to be hereinafter describedand claimed. 7

The invention will be best understood by reference to the accompanyingdrawing, showing the preferredform of construction and in which:

Fig. 6 is a perspective detail view of the 6'5 blade employed in theembodiment of the ii1 vention illustratedin Fig. 5; and I Fig. 7 is afragmental view-depicting the interlocking of the blades to beemployedin M the holder asdepictedfin Fig. 5. v I d'o In theaccompanying drawing wherein I have illustrated a preferred form ofcon.- struction for myinvention, 10 generically indicates a typical meatgrinder which includes a mouth portion 11 through which "65 materialtobe ground or cut in the device may be introduced into the. relativelyelongated neck portion 12. A feed screw 13 isarranged on the shaft 14and said shaft has one end portion 'journaled inthe bearing15 atpnefl)end of the relatively'elongated neck 12. A

handle 16 is secured to the end io f'the-sh'aft i 1% which extendsbeyondthe bearing 1:5 b y thewing nut 17. The opposite end of" the shaft'l isreduced as indicated at 18 and 56.

thisreduced portion is extended 'throughthe perforated plate 19 which isheld'against rotative movement the lug 20 that is fitted in a recess inthe adjacent 'endof' theineck portion 12. While'the fore oingdescription is depicted it is to be understood that this'is not to betaken as a limitation'of my inven tion since any desired arrangement maybe substituted in place of that shown without departing from the purviewof my invention.

Asis well understood in the art the material introduced into the mouth11 is forced through the neck portion 12 by the feedls'crefv'v 13 whichforces the material past a cutting implement 21 throughthe'p'erforations n the plate19. As themat'erial passes the. out i tingimplement 21 and-travels through the perforations 19 the cuttingimplement acts on i the material with a shearing action and in thismanner'the material is chopped or ground. g g Y w p The cuttingimplement I employ mmy improved device is genericallyindicated 21.;

By referring to Fig. -2 it may be seenthait a substantially'square'opening 22is "formed 2 in the cutting implement 21 which is fitted overa correspondingly shaped portion on the shaft 14 and which is retainedin position by a nut 23. While I have depicted this arrangement forsecuring the implement 21 in position it is to be understood thatanalogous arrangement-s .might be employed without departing from thepurview of nay-invention.-

' In the presentinstance the. cutting implement 21comprises four arms23, 24, 25, arid 26. angles with respect to-the arms 24:. and 26.Preferably the arms 23-and -are arranged so that one edge of the arm 23will .bealigned with the opposite edge of'the arm '25. The {arms 2land26are similarly disposed so that ,one edge "of the arm 24 :will be alignedwith the-opposite edge of the .arm 26.

' By referring to Fig. 3 it may be seenthat ia.;groove;27 is formed inthe arm 25 in the upper surfacethereof.v Grooves similarto the groove:27..are similarlydisposed in each of; lletrarmsl23, 2st; and .26 andthese grooves serve to retain the cutting blades in position.

tion with: one endofthe blade 28 a portion 32 isstruck outwardly inthedirection of the bend and. this portion is arranged so as to:be-disposed closer to one end of the blade 23 than-the other. Formed ineach of the arms 23, 24:, 25,.and26 at a-pointspaced from theaolltwardlydisposed end thereof substantially 7 equal to thedistancebetween the out struck Q5 p ortion32. andfthe end of the bladedisposed anost remote .from tlnsport on and inthe .portwn .of'the-armsintermediate the groove 27 andfthe juxtaposed-edge I form notches 33whichextend downwardly from the upper edges. These notches-33 areutilized in the following manner. VVhen=the blades 28 are-.arranged-with the portions .29 thereof in the grooves 27 the outstruck portions 32 ;fit:into therecesses 33. This fittingpreventsmovement longitudinally. of the blade in the slot 27. Thefitofthebladesin the slot is preferably suchthatsufficient tension will be exerted onthe blades to prevent their mov ,ingoutwardly from the slots.

, When thecutting implement 21 having the blades 28 thereon is arrangedin abutment .Withthe plat-e19the'blades28 are disposed sojthat thecuttingedges 31 thereon will travel over the plate -19 so as to producethe sheari'in-gwactionset forth and in thisimanner the The arms 23 and25 extend at right- The foregoing arrangement is employed in.

the cutting implement are retained against displacement when the deviceis so arranged and it is also manifest that these blades may beexpeditiouslyi r moved for replacement, sharpening and the like. It isalso manifest that-the notch '33 one arm is arranged in alignment withthe groove 27 in the arm extending toward the maj or extent of the firstnamed arm. and this is the preferable "d1s-' positionof these notchesalthough it is manifest that these notches might bearranged n "otherpositions in the embodiment of the invention without departing'from thespirit and scope of the invention.

In the embodiment of the invention illustrated in detail in'Figs. 6, and7 theholder ,heremtofore set forthisconstruoted 1nidentical manner.However, in this instance it is necessary that the notches 33 'be'aligned with the grooves in the mannerhereintofore set forth forapurpose that will be made apparent presently. In this embodiment of theinvention blades generically lndicated by 3 Lare employed which embodyaportion '35 similar to the portion .29 and a; portion 36 similar totheportion some a cutting edge 37 similar tothecutting'jedge 31. ;Atsubstantially the same location in the blade '34 as the location ofth'eout struck portion 32 in'the blade '28- in the lower edge thereof I forma recess 33. ()n theinwardlydisposed .end of the bladeiil 1 formanoutstanding lug 39. Whenone of the blades 34: is disposed in thegroove 27 0f the arm 25 the 27 in thearm 24. Therefore, when a blade3etfis arranged finithe groove 27'of the, arm

24 the notch .33 in this last named blade 34:

willfit over the lug 39 in the groove 27 of the arm 24 which is the lug39. on the blade3l disposed in the groove 27 ofthe arm 25. It is notnecessary that the lug 39:

extend intothe notch 33 since this .lug is merely intendedto it into thenotch '38 of the lde 3a which extends at right angles .to the bladecarrying the lug. in a manner substantially similar to that set forththe lug39 on the blade 3ldisposed in the groove 27 of the arm 24%isfitted into the notch 38 ,of the'blade 34 disposed in thegroove 27 ofthe arm 23. In a similar manner thislast named blade 1S interconnectedwith theblade disposed in the groove 27 of the arm 26 and.

between the blades by reason of the lugs 39 and the notches 38 it ismanifest that the various blades will be securely retained in position.

While I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modification, without departing from the spirit of theinvention. I, therefore, do not wish to be limited to the precisedetails of construction set forth, but desire to avail myself of suchvariations and modifications as come Within the scope of the appendedclaims.

Having thus described my invention what I claim as new and desire toprotect by Letters Patent is: p
